Position Precision with CPI SL Series
In the more than 20 years CPI has been developing the world’s most robust and durable underwater draw wire position sensors , it’s fair to say we’ve learned a few things. For subsea hydraulic cylinders and hydraulic accumulators the use of specialized draw wire sensors like ours are likely to be the system designer’s best choice. Our unique measurement technology can cover stroke lengths anywhere from 1 meter to almost 30 meters (100 ft) while completely submerged in water or hydraulic fluid. They can operate inside or outside of a hydraulic cylinder. Our sensors have functioned everywhere from the corrosive salt water of rig raisers in the Gulf, to the corrosive chlorinated water of a Las Vegas Swimming pool! The primary requirements of these applications end up being the durability and reliability of these sensors in their underwater environments but a close second is the requirement for accuracy and precision in the sensor as it mechanically extends and retracts over as much as
